Pilots of the t-50 will protect unique antiperegruzočnye costumesNew equipment will allow pilots to perform maneuvers with overloads and 9 g at an altitude of 23 km catapult
Russian fifth-generation fighter t-50 had a unique protective gear, pilot-induced pressure on the body during prolonged overloads. The kit, designed by OAO «NPP "Zvezda", consists of two protivoperegruzočnyh costumes and light pressure compensation system allows you to make maneuvers with overloads 9 g for a period of up to 30 seconds. The Catapult of the machines will be at an altitude of 23 km.

As told by Izvestia "stars Deputy Chief Designer Nikolay Dergunov, pilots will protect the two flight-suit: RFP protivoperegruzočnyj-7 and high-altitude compensating WCC-17. They choose before your flight depending on the height-PPK-7 runs at an altitude of up to 12 thousand meters, and WCC-17 — up to 23 thousand.
Both costumes are connected tothe state machine pressure ad-17, which inflates the air cavity costumes overloads and begins to supply oxygen pressure in the respiratory mask.
According to Izvestia, the Chief specialist of the JSC "SPE star Michael Dudnik, the oxygen pressure in the mask when overloads is 6-7 atmospheres. The pilot's lungs are inflated from within, so offset by external pressure on the rib cage. The on-board computer foresees overload and enables you to avoid the lag compensation system pressure.

Is This development — our know-how, while no one in the world to develop such a system could not explained Dudnik.
Protivoperegruzočnyj is a high-altitude suits and coveralls made of termostojkoj fabricssewn in with cameras and tubes.While performing maneuvers through these tubes is air that inflates costume. Fabric compresses the body of the pilot and prevents outflow of blood from the head. If this is not done, the pilot momentarily lose consciousness.
According to test pilot Sergei Bogdan, the hero of Russia who first picked up the t-50 is in the air and its testing in the new plane because the pilot sverhmanevrennosti without compensation of pressure perish when spreads and bends.
— Overloading 9 g is your weight increasing by nine. When there is an overload, the chest instantly compresses and very difficult to breath. When it lasts for 2-3 seconds, yet wherever went, but when 20-30 — withstand pressure without compensation cannot be explained by Bogdan Izvestia.
In a high compensatory suit fabric more dense, there is a special insulation, allowing the pilot to survive when the depressurization or katapul′tirovanii at an altitude of up to 23 km To the pilot's body.high-altitude suit equipped with ventilating vest. But even with himin such a suit is hot, so fly to the small height pilots prefer Lite protivoperegruzočnyj.
Air supply system and automatic pressure has mounted in the last three experienced t-50. factory testing Suits are now under way and will soon be transferred to thepilots-verifiers — Sergey Bogdan plans to try on your own copy next week.
